League of Legends patch 12.15 is scheduled to go live sometime next week, and Riot Games has a fair bit of updates planned for the upcoming update.While 12.15 will not be completely upsetting the current champion meta, it will, however, introduce a fair bit of tweaks to smoothen things out for some of the champions in the game.Matt Leung-Harrison@RiotPhroxzonNotable: We're happy with where Yi has ended up across skill brackets, but he's too strong across the board.
